Margin of Safety concept as applied to common stocks, under depression conditions

There are instances where a common stock may be considered sound because it enjoys a margin of safety as large as that of a good bond.

1. This will occur, for example, when a company has outstanding only common stock that under depression conditions is selling for less than the amount of bonds that could safely be issued against its property and earning power.
2. That was the position of a host of strongly financed industrial companies at the low price levels of 1932-33.
3. In such instances the investor can obtain the margin of safety associated with a bond, plus all the chances of larger income and principal appreciation inherent in a common stock. (The only thing he lacks is the legal power to insist on dividend payments “or else” – but this is a small drawback as compared with his advantages.)
4. Common stocks bought under such circumstances will supply an ideal, though infrequent, combination of safety and profit opportunity.
5. As a quite recent example of this condition, let us mention once more National Presto Industries stock, which sold for a total enterprise value of $43 million in 1972. With its $16 millions of recent earnings before taxes the company could easily have supported this amount of bonds.
